The error message you are getting indicates the amount of local withholdings exceeds the actual local earnings.
Does your W-2 form indicate the amount of your local wages anywhere else on the form?
If so, enter that information into box 18. If not, you should contact your employer to determine if there should be an amount in box 18 and if so, use the amount they provide to you to ensure your local taxes are calculated correctly if you have a reporting requirement for your state.
If not, you may need to delete your W-2 input and re-enter it as this also could rectify the issue if your W-2 form is reported correctly.
